Our Vision

Vision Statement

The heat pump “revolution” has already begun (growing globally at 8.5% per year). It promises dramatic savings for heating appliance operating costs through major leaps in energy efficiency, using climate friendly methods to promote human comfort.

However, electrically-driven heat pumps (the most common so far) have limitations. They cannot match the comfort and economy of conventional furnaces and boilers in cooler climates. Thermally-driven heat pumps (using natural gas, propane, fuel oil, bio-fuels, and even the sun) – provide the energy and climate benefits of heat pumps without sacrificing comfort or convenience – and are now poised to join the revolution.

Over the next decade, thermally-driven heat pumps will replace furnaces, boilers and gas water heaters as the dominant method of supplying the world’s heating needs.

Are you ready to join the revolution?


SMTI has developed cost efffective and scalable component designs that enable sorption heat pumps to compete against “standard” direct-fired heating systems.
Sorption heat pumps are powered by a heat source – natural gas, waste heat, even solar. Sorption heat pumps can provide heating, cooling or refrigeration. Sorption heat pumps use natural refrigerants with Zero GWP and are cost effective for gas-fired heating and heat/solar-fired cooling/refrigeration.

Business Vision
